This project is the skeleton for the creation of a game using the Game Engine Toolkit of CodinGame.

Check the documentation on the github repository.

Note about the game turn implementation

There are 2 ways to implement your game turn according to the game you want to create. The simultaneous mode or the Turn by Turn mode.

The simultaneous mode

It's a game mode where all players receive the game data and execute their actions in the same turn. (eg: Race, Pong, ...)

for (Player player : gameManager.getActivePlayers()) {
    player.sendInputLine(input);
    player.execute();
}

for (Player player : gameManager.getActivePlayers()) {
    try {
        List<String> outputs = player.getOutputs();
        // Check validity of the player output and compute the new game state
    } catch (TimeoutException e) {
        player.deactivate(String.format("$%d timeout!", player.getIndex()));
    }
}

// Check if there is a win / lose situation and call gameManager.endGame(); when game is finished

The Turn by Turn mode:

It's a game mode where only one player execute an action during a turn. (eg: TicTacToe, Chess)

SkeletonPlayer player = gameManager.getPlayer(turn % playerCount);
player.sendInputLine(input);
player.execute();
try {
    List<String> outputs = player.getOutputs();
    // Check validity of the player output and compute the new game state
} catch (TimeoutException e) {
    player.deactivate(String.format("$%d timeout!", player.getIndex()));
    player.setScore(-1);
    gameManager.endGame();
}

// Check if there is a win / lose situation and call gameManager.endGame(); when game is finished

Loading assets

Assets are expected to be placed in the src/main/resources/view/assets folder of your game's project.

You can then use the images in the texture cache with the Entity Module:

entityManager.createSprite.setImage("background.jpg");
